Jason Mraz Stunned By Jonas Track

Jason Mraz was left stunned by a Nick Jonas tune performed in the Disney TV movie Camp Rock 2 : The Final Jam - because parts of it sounded just like his hit I'm Yours.

The singer is convinced the acoustic track, Introducing Me, was inspired by his own Grammy-nominated tune - but the laidback star insists he can't be bothered to take legal action over the matter.

He tells FemaleFirst, "I heard the song, and it was just a tremendous, tremendous horror of a tune. I noticed a few similarities in the melody, but it wasn't enough to pick up the phone and argue with somebody about it. If anything, I just wanted my $1.29 back that I spent on iTunes."
